Advanced technology for cooling the world’s fastest CPUs

If you’re serious about high-performance computing and overclocking, you already know that you’ve got to keep your PC’s processor cool. In order to do this you need a CPU cooler that not only outperforms your current heatsink, but also does it quietly.

The Hydro Series H70 has been designed to deliver exceptional levels of cooling performance, and to provide significant headroom for overclocking your processor, quietly and reliably.
The Hydro Series H70 is an evolution of the award-winning Hydro Series H50, with several significant upgrades that enable it to deliver even greater cooling performance. These upgrades include a thicker 120mm radiator unit (50mm) with a higher heat-exchanging capacity, and a more efficient, low-profile pump/cold-plate unit that can soak up more heat and provide even lower CPU temperatures. The Hydro Series H70 also features two speed-switchable 120mm cooling fans in a push-pull configuration to provide powerful cooling airflow at low noise levels.
The Hydro Series H70 is compatible with all current CPU socket designs, including Intel LGA775, LGA1156 and LGA1366, and AMD Socket AM2 and Socket AM3.

Key Features

120 x 50mm Radiator
The Hydro Series H70 uses a high-quality 120mm radiator unit that is double the thickness of the radiator used in the Hydro Series H50. The increased thickness of the radiator unit, compared to the H50, equates to a larger internal volume and hence higher coolant capacity. The total surface area of cooling fins is also vastly increased. Both of these upgrades contribute to significantly higher cooling capacity compared to the H50 and other high-end HSFs.

High Performance Copper Cold Plate
The Hydro Series H70 utilizes an improved copper cold plate, which is directly integrated into the pump unit. The high-quality cold plate soaks ups heat from the CPU and dissipates it into the coolant via copper micro-channels. This provides significantly higher cooling capacity compared to the Hydro H50 and traditional heatpipe-based HSFs.

Low Profile Pump Unit
The Corsair Hydro Series H70 utilizes a low-profile pump / cold-plate unit. This compact, high-performance pump unit not only allows the H70 to be used in a wide range of systems / chassis, where the size of many premium HSFs would be prohibitive, but it also places no stress on the motherboard for better overall system reliability.

Push-Pull 120mm Fans
The Hydro Series H70 utilizes two high-quality 120mm cooling fans in a push-pull configuration. The fans are speed-switchable between 2000rpm for maximum cooling performance and overclocking flexibility, for enthusiasts who want to push their CPUs to the limit, and 1600rpm for those who want a balance between powerful cooling performance and low sound levels.

Performance
The following results are indicative of the level of performance that you should expect to see from the Corsair Hydro Series H70 CPU cooler at full fan speeds. All data was gathered at an ambient temp of 25 Degrees C, or roughly 77 Degrees F, with a minimum log time of 120 minutes per test.

The H50 deltaT was 60C, while the H70 deltaT was a much lower 46.7C. This difference of 13.3C is largest at overclocked, fully loaded settings. At lower clock speeds and idle temps, the difference is less pronounced.

Test system: Intel Core i7-920 processor overclocked to 3.8GHz (20 x 190MHz, 1.34V vcore), Asus Rampage III Extreme Motherboard, inside an Obsidian 800D case with default fan configuration (save for the rear fan which was removed to accommodate for the H70 installation as detailed above).
